How I Stopped Guessing Payment Failures in ASP.NET Core (Free Tool)

Payment integrations rarely fail loudly. They fail silently. A webhook doesn’t arrive. A payment status changes unexpectedly. A duplicate event overwrites valid data. And suddenly, you're debugging production logs at 2 AM. After facing these issues in a real payment gateway integration (Worldpay), I decided to build a centralized logging system specifically for payment events in ASP.NET Core. The Real Problem Most payment integrations suffer from: Scattered logs across controllers and services No structured audit trail No visibility into status transitions Duplicate webhook events Painful post-incident debugging Traditional logging isn’t enough when money is involved.
